Zusammenfassung:PURPOSE: To endure against the load of a large-sized vehicle and to prevent the damage of a pipeline by inserting a plastic long tube into the tube inserting hole of a tube coupler having engaging groove and stripe on the periphery of a rectangular frame, simultaneously coupling a plurality of the adjacent couplers, and mounting a load receiving protective beam via a protective beam mounting seat on the coupler of the uppermost stage. CONSTITUTION: A tube coupler 2 has an engaging stripe and grooves 6, 7 at the centers of left and right side faces 4, 5 of a rectangular frame 21, and an engaging stripe and grooves 10, 11 at the centers of the upper and lower surfaces 8, 9. A plastic long tube 1 is inserted to the tube insertion hole of the coupler 2. A plurality of plastic long tubes 1 are respectively inserted to the couplers 2, which are coupled to each other to be simultaneously coupled. A protective beam seat 15 is placed on the upper surface 8 of the coupler 2 of the uppermost stage of the thus coupled coupler 2, and a load receiving protective beam 20 is engaged fixedly on the seat 15, and hence the beam 20 can be provided in parallel above the tube 1.
